Question

A square and a rectangle have same perimeter. If the side of the square is 60 cm and length of a rectangle is 80m, then whose area is more and how much?

Answer 1

perimeter of square is equal to 60 × 4 =240
let the breath of rectangle be b
perimeter of rectangle =2(l+b)
240=2(80+b)
120=80+b
120-80=b
40=b
area of square=3600
area of rectangle=3200
difference is 400

Answer 2

Answer:

Step-by-step explanation:

So perimeter of square is equal to the perimeter of rectangle then= 60 × 4 =240

let the breath of rectangle be b

perimeter of rectangle =2(l+b)

(As perimeter are equal)

240=2(80+b)

120=80+b

120-80=b

40=b

area of square=3600(a square)

area of rectangle=3200(l×b)

Then difference =3600-3200

=

difference is 400
